SPOTLIGHT.

Application filed March 12, 1923.

To all whom 'it may concern.'

Be it known that we, Gusrar E. KRANTZ and Clint. A. KRANTZ, citizens ofthe United States, residing at Chicago, in the county of Cool; and Stateof Illinois, have invented certain new and useful Improvements inSpotlights7 of which the following is a speciiication.

This invention relates to improvements in spot lights, and one of theobjects of the same is to provide an improved spot light particularlyadapted though not necessarily limited in its use for attachment to thewind shield or screen of an automobile, the light V being disposed onone side of the shield and shifting mechanism therefor being arranged onthe other side of the screen, the light and operating mechanismtherefor' being connected through the shield or screen, the

whole being supported by the shield at a point within the contines ofthe edges of the shield.

A further object is to provide an improved light of this character,which is adapted to stand in close proximity to the face of the shield-or screen and to be shifted at will from any of its positions to aposition at an angle of substantially 90o1 thereto, thereby enabling`the driver to turn the light so as to inspect objects or numbers ofresidences, the fronts of which residences are parallel with the line oftravel of the vehicle.

A further object is to provide an improved light of this characteradapted to be readily1 installed or mounted upon any wind shield.

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists in the features ofnovelty in substantially the construction7 combination and arrangementof the several parts hereinafter more fully described and claimed andshown in the accompanying` drawings illustrating this invention and inwhich Figure 1 isa front elevation of the spot light showing the same asmounted upon a wind shield and also showing the light in dotted lines inanother position.

Figure 2 is a horizontal, sectional view taken on line 2-2, Figure 1,showing the light in fnll lines in one position and in dotted lines inanother position.

.Figure 3 is a vert-ical, sectional view taken on line 3-3, Figure 1.

Serial No. 624,369.

Figure 4t is a detail sectional view taken on line 4%, Figure 1.

Figure 5 is an elevation of a detail.

Figure (3 is an end elevation of Figure 5.

Referring more particularly to the drawings. the numeral 10 designatesthe wind shield of an automobile, which is usually constructed of glassand the shield is provided with an opening 11 therethrough at anydesired or convenient position.

The light casing designated generally by the reference numeral 12 may beof any desired or suitable configuration and construction in anysuitable manner and is mounted upon an operating arm or lever 13, theextremity 14 of which is preferably shaped to form a handle.

rl"he arm or member 13 is preferably pro-v vided midway of its lengthwith laterally projecting lugs or trunnions 15 adapted to be seated inseats 16 in co-operating members 17, the latter being provided withopenings 18 therethrough. rlhese members 17 are arranged on oppositesides of the trunnions 15 and are of any desired size and configurationand constructed of any suitable material preferably metahvtheirdiameters heilig somewhat less than the diameter of the opening 11 inthe shield 10.

The seats 16 are preferably of a depth somewhat less than one-half thediameter of the trunnions 15 se that when the members 17 are assembledthey will be spaced from each other for a considerable distance as shownmore clearly in Figure When the members 17 are assembled the arm orlever 13 will project through the registering openings 18 and themembers 17 may be secured together by suitable fastening devices 20,such as screws or the like. One of these fastening devices 20 ispreferably provided with a lnurled head 21 on one extremity on .one sideof one of the members 17 and is threaded into a nut 22 on the other sideof one of the members 17.

It is obvious that with this construction, the members 17 may be forcedtoward each other by the adjustment of the screw 20 so as to cause agreater amount of friction to be exerted by the walls of the seats 16upon the trunnions 15 and thereby clamp the lever 1-3 against pivotalmovement with respect to the members 17, so as to hold the lamp 12 inits adjustedl position about its pivot. By loosening the screw 20 thefriction will be relieved and the lamp may be swung readily about itspivot.

The nut 22 is adapted to be held against rotation to permit adjustmentof the screw 20, in a manner as will be hereinafter set forth.

The members 17 are adapted, when the lamp is secured in position tostand within the opening 11 in the shield 10 and are preferably soarranged that they will stand within the planes of the faces of thescreen.

Annular clamping members 23 are disposed on opposite sides of the shield10 and the openings 24Min the annular members are of a diameterconsiderably less than the diameter of the opening 11 in the shield 10and also less than the external diameter of the members 17, so that whenthe clamping members 23 are placed in position they will engage thescreen or shield 10 and also the lateral faces of the members 17.

The clamping member 23 are adapted to be secured in position in anysuitable manner such as by means of fastening devices 25 in 'the form ofscrews or the like which pass through the openingy 11 and engage eachother so that when the screws 25 and nuts thereon are tightened theclamping plates 23 will securely hold the members 17 in position tosupport the light 12.

If desired annular washer members 26, of any desired material, such asfibre or the like may be disposed between the clamping members 23 andthe proximate faces of the shield 10 and these washer members 1G areadapted to rest against the proximate faces of the members 17 to formfrictional contact therebetween and thereby frictionally control therotation of the members 17 within the opening 11.

1f desired the members 17 may be split as at 27 and deflected as at 28to form yielding friction surfaces contacting with the washer members16.

The nut 22 is preferably provided with a flattened surface 28*L as shownmore clearly in Figure 1, and this flattened surface engages the innerperiphery 29 of one of the members 23, so that the nut 22 will beheldagainst rotation when the screw 20 is adjusted and at the same time thenut 22 will not interfere with the rotation of the members 17 within theopening 11 of the-screen 10.

The lever or member 13 is preferably provided with a passage 30itherein, within which the conductor 31 which is connected with the lamp32, isadapted to be located for the protection of the former. As a meansfor controlling the light 32 a suitable switch 33 maybe provided, whichis located inl any. convenient position for the'operator preferably uponthe handle end 111 of the lever 13 andin a position so that when theoperator grasps the handle 111 he may manipulate the switch 33 with thethumb of the hand which grasps the handle.

The lever 13 is so shaped and the trimnions 15 are so arranged that whenthe lamp is in the position shown in Figures 1 and 3, it will stand inclose proximity to the shield 10 and by loosening the screw 2O the lampmay be swung by means of the handle 14C about its points of pivotalconnection with the members 17 and by adjusting the screw 20 the lampmay be clamped in its adjusted position.

Vhen the parts are in this position the operator may bodily rotate thelamp 12 by means of the handle 14 so as to rotate the members 17 withinthe opening 11, thereby permitting the operator to move the lamp 12 fromthe position shown in full lines in Figure 1 to the position shown indotted lines in the same figure or to any intermediate position, and toeither side of the pivot. When the lamp has assumed the position shownin dotted lines in Figure 1 and in full lines in Figure 2, the operatormay then swing the lamp about its pivot from the full line position inFigure 2 to the dotted line position or for a distance of substantially90, thereby permitting the operator to inspect objects or numbers ofresidences, the fronts of which residences are arranged parallel withthe line of travel of the vehicle.

It will be manifest that with this construction tlie lamp is adapted fora universal movement and can be switched or moved to` made in thedetails of construction and in the combination and arrangement of theseveral parts, within the scope of the claims,

without departing fromthe spirit of this invention.
